Playwright reports Error: No tests found after fresh install

Describe the bug

Running the npm create svelte@latest script and then attempting to run the playwright tests gives an error.

$ playwright test
[WebServer] 
[WebServer] 
[WebServer] 
Error: No tests found

I tried with various combinations such as the "App" template and the "Library" template, as well as Typescript v.s. Javascript. And they all show that same error even though there appears to be a default test at:

tests/test.ts or tests/test.js

Reproduction

Run the following:

npm create svelte@latest my-app
cd my-app
npm install
npm run test

Logs

> npm create svelte@latest my-app
cd my-app
npm install
npm run test

create-svelte version 4.1.0
